The ATC-50 report, Simplified Seismic Assessment of Detached, Single-Family, Wood-Frame Dwellings, was funded by the City of Los Angeles and by a Federal Emergency Management Agency Hazards Mitigation Grant from the California Governor's Office of Emergency Services. (Published 2002, 2007, Second Printing, 118 pages)

ABSTRACT: The report provides inspection procedures and a four-page Simplified Seismic Assessment Form to evaluate detached single-family wood-framed dwellings and to assign to each a seismic performance grade. The procedure considers the potential for damage or collapse in a manner that is consistent and useful to owners, purchasers, insurers, lenders, contractors, design professionals, and regulatory officials. The report development effort included a pilot testing program whereby 500 dwellings in the City of Los Angeles were evaluated using a preliminary version of the Simplified Seismic Assessment Form. The purpose of the Pilot Seismic Assessment Testing Program was to evaluate the utility and ease-of-use of the Form, and results from the pilot program were used to update the Form.
